Hi Guys!
Sorry to say I'm having problems with my recently purchased Yamaha PSR SX700. Purchase 2/26/2020
For the last couple of weeks, when I turn it on, It plays OK for a while and then all of a sudden, every key I play has a reverb sound as if someone had turned it on and cranked it up to full volume. At that point, all tones becomes muddled and annoying.
Today 8/12/2020 I turned it on and played with it for about 15 minutes. Then I left it on while I had to go and eat dinner.
After I returned, there it was ... all keys have a reverb behind them (even if I change instruments).
I can fix it by turning off the Keyboard, wait a few seconds and turning it back on again.
I think that I should contact Yamaha while it's still under warranty. I hesitate to call my dealer and as you know, I've had problems with him.
What do you all think? Thanks
